I broke down at my daughters just before Christmas. It drove there fine and I turned the engine off whilst I was waiting to collect my grandchildren but then wouldn’t turn back on. The AA man couldn’t figure out what the problem was but he managed to bypass everything by starting it up with a jump direct from the battery to the starter motor. I now think my immobiliser may be part of the fault. All fuses seem good and wires look ok. Any ideas has this happened to anyone else. Any help would be appreciated x
